Advanced environmental protection PP strapping is inevitable for market development

Packing tape is make of BOPP and Acylie, it was transparent and has strong stick, it can be divided into transparent A grade, transparent B grade, and A grade from the quality of the product. , AB grade, B grade, BC grade and C grade, etc; from the use of the machine can be divided into hand playing belt, machine playing belt (also divided into automatic machine playing belt and semi-automatic machine playing belt); from the use of the scope of Divided into packaging with packing belts and crafts belts; there are printing and non-printing belts and so on.
PP is used as the packing material, mainly because of the chemical and physical properties of PP polypropylene. The Chinese name of PP is polypropylene or acrylic resin, and the English name is Polypropylene Resin. PP is a semi-crystalline material. It is harder and has a higher melting point than PE. The Vicat softening temperature of PP is 150C. Due to the high degree of crystallinity, this material has very good surface stiffness and scratch resistance. At the same time PP has excellent formability and mechanical strength higher than PE. Polypropylene PP has good water resistance, chemical resistance and electrical insulation.
Since PP is an accessory product of oil, the price will be largely influenced by the price of oil. From an environmental point of view, resources are limited, which requires that all manufacturers need to be able to recycle to save resources. The environment-friendly packing belt is not filled with any filling and impurities. After use, it can be crushed and used again. In general, many of our common inexpensive packaging belts contain dozens of fillers. In other words, the inside is full of rubbish, this packing belt is only a thin layer of PP material that is better, but can not be recycled after use, how can the effect of recycling be imagined. Therefore, from the perspective of long-term and environmental protection, it is inevitable that the production and extensive use of environment-friendly high-grade packing belts and step-by-step replacement of core tapes (regeneration belts) are inevitable.
